OpenBuild Acme screw for Z-Axis

Use Inventables supplied pulley.
However you also need the lock collars.

The rod is already an 8mm diameter. So the included 8mm pulley already fits. I used the anti-back lash Delrin nut from Open Builds. I also added a lock collar at the bottom underneath the flange bearing. [image]

I have that rod and anti black lash nut on my machine
